Run a minimal test for JUST `mcp_tool_call`: - - Does Codex emit `function_call` or `mcp_tool_call`? - - What's the EXACT shape of the event? - - Log: `console.log("RAW EVENT:", JSON.stringify(event))` - - 3.

RESULT: Test `maps thread/item events for file changes, MCP tools, web search, and todo lists` passed on first run (28461ms) when API was available. Current failures are due to Codex API rate limit (429 Too Many Requests, `usage_limit_reached`) which resets at 1766651941 (~2 hours). Thread/item mapping implementation is correct - handles `file_change`, `mcp_tool_call`, `web_search`, and `todo_list` via `mapRawResponseItemToThreadItem` and `threadItemToTimeline`. EVIDENCE: `npm run typecheck --workspace=@paseo/server` (passes), debug run showing `error` event with `codex_error_info: "usage_limit_exceeded"`, first test run showing `✓ maps thread/item events for file changes, MCP tools, web search, and todo lists 28461ms`. - [x] **Fix**: Typecheck error in `agent-projections.ts:198` - {} not assignable to JsonValue.
